CHURN DASHER.

SPECIFICATION forming part of Letters Patent No. 271,301, dated January 30, 18783.

Application filed October 3, 1882. (No model.)

To all rwhom it may concern:

Be it known that I, CONRAD BERST, a citizen of the United States, residiugat Princeton, in the county of Mercer and State of Missouri, have invented certain new and useful Improvements in Churn-Dashers, of which the following isa specificatiomreference being had therein to the accompanying drawings.

Figure 1 is an end elevation of my improvufed churn-dasher. Fig. 2 is a sectional view taken on lines x 50,'Fig. 1. Fig. 3 is a top plan view, a nd Fig. 4 is a bottom plan View, further showing the construction and arrangement ot' parts.

Similar letters denote like parts.

M v invention relates to improvements in the construction of churn-dashers; and it consists in certain novel details of construction and arrangement by means of which the operation ot' churning may be facilitated, as will be hereinafter more particularly described.

A represents the stem or handle of my improved churn flasher, and it passes down through a vertical chamber between the parts, and is secured to the cross-bar B. 'lhe vertical chamber referred to is formed by two side pieces'of the dasher and the perforated stationary slats or ribs C C', that extend across the dasher, and are secured to the side pieces, D D, to which side pieces are also secured the top covering-boards, E E', which close the space between the side pieces up to the perforated slats or ribs C C', the only passage through the dasher being through the vertical chamber between the said slats C C. The slats are provided with lateral perforations, through which liquid can enter to vertical chamber only in horizontal streams.

rlhe detecting-plate F is a strip of wood or other suitable'material, and is secured to the stem A about half an inch (more or less) above the chamber, between the horizontaly-perfo rated ribs C C', and it is slightly Wider and longer than the said chamber, but not longer than the width ot' the dasher. As the dasher .t5

is `forced downward through the cream the same is thoroughly stirred, mixed, and shaken up, as follows: That portion of the cream beT tween the side pieces and their covering-boards E is forced through the perforationswo iu hori- 5o zontal streams from both sides, which streams meet with considerable friction from the sides of the perforatipns as they pass through, and as they emerge into the central chamber they impinge against and around the cross-bar B 55 and a double stream passing upward, with which they mingle and are carried up. The whole upward current strikes the detlectingboard F, and is thereby divided and spread out evenly on both sides in two thin flat 6o streams. Should the friction caused by the horizontal streams impinging against the vertical stream and the consolidated stream striking the detlecting-board F not be sutcient to quickly reduce the cream to butter, the open- 6 5 ings and central passages may be made smaller.

Having described myinvcntion,whatIclaim, and desire' to secure by Letters Patent, is-

1. A churn-dasher formed with covered end 'chambers communicating by horizontal p erfo- 7o rations with a central vertical chamber, provided with a strip or bar secured in the bottom of the lower portion and adapted to divide the entering upward current, and a defiectingboard located close above the top ot' the said 75 central chamber, substantially as described.

2. In a chnrn-dasher, the combination, with the sides D, cross-bar B, handle A, and deflect ing-board F, of the horizontally-perforatedribs C C, and covering-boards E E", substan- 8o tiall y as described.

In testimony whereof Iaftix my signature in Y presence ot' two witnesses.

CONRAD BERST.
